Direct seeding

Direct seeded crops require less labor and tend to mature faster than transplanted crops.

In this method, plants are not subjected to stresses such as being pulled from the soil and re-establishing fine rootlets. However, they have more competition from weeds.

Depending on the land preparation method used, direct seeding can be done in two ways:

Dry direct seeding

This method is usually practiced for rainfed and deepwater ecosystems. Farmers sow onto dry soil surface, then incorporates the seed either by plowing or harrowing.

  • Broadcastingplanting-broadcasting
    1. Broadcast 60−80 kg of seeds uniformly by hand or in furrows in 1 ha of field.
    2. Make shallow furrows by passing a furrower along the prepared field.
    3. After broadcasting, cover the seeds using a spike-tooth harrow.
  • Drilling

Precision equipment, such as the Turbo Happy Seeder, can be used to drill seeds.

Drill 80−100 kg of seeds per ha.

Seeds are placed by the machine into both dry and moist soil, and then irrigated. A smooth, level seedbed is necessary to ensure that seeds are not planted at depths greater than 10−15 mm.

In this technique, fertilizers can be applied at the same time as the seed. Manual weeding also is easier in machine-drilled crops than in broadcast crops.

  • Dibbling

Dibbling or hill planting is usually practiced along mountain slopes or where plowing and harrowing are difficult.

  1. Use a long wood or bamboo pole with a metal scoop attached at the end for digging holes.
  2. Drop the seeds into the holes and cover them with soil.


Direct seeded rice have more competition from weeds. Weeds can be controlled through the following:

This technique is best if the field has a large weed seed bank.

It can greatly reduce the weeds in DSR because of the 2–month fallow period between harvest and sowing, which allows weeds to emerge before they are killed.

This technique is also helpful in managing weedy rice.

list collapse Use of herbicides

The choice of herbicide depends on the type of weeds. No single herbicide can control all weeds in the rice crop.

For effective weed control, apply a pre-emergence herbicide, 1–3 DAS. While post-emergence application should be at 15–25 DAS.

list collapse Weeding by hand or by machine

Weeds are practically impossible to control by manual weeding by hand. However, one or two spot hand weeding can be done to (1) remove weeds that escape herbicide application, (2) prevent weed seed production and the accumulation of weed seeds in the soil.

In mechanical weeding, motorized cono and other hand weeders can be used.
